90014-05-4 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 90014-05-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 9,0,0,1 and 4 respectively; the second part has 2 digits, 0 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 90014-05:
(7*9)+(6*0)+(5*0)+(4*1)+(3*4)+(2*0)+(1*5)=84
84 % 10 = 4
So 90014-05-4 is a valid CAS Registry Number.
